Amazon's Getting Started with FBA guide lists the templates you can choose when you print item labels, and adds one instruction: print the labels without scaling.

The US size: 1 × 2⅝ in, 30 per sheet
The only US Letter template is 30 labels per page. Its geometry is the same as Avery 5160 (laser) and Avery 8160 (inkjet): three columns of ten labels, each 2.625 in wide and 1 in tall, with a 0.5 in top margin, 0.1875 in side margins and 0.125 in between columns.
On that label our generator draws the Code 128 bars 47.8 mm wide with a 0.33 mm narrow bar, which leaves 9.4 mm of blank label on each side of the bars.
Thermal roll sizes
Seller Central has no roll template, so a thermal label is something you produce yourself from the FNSKU. The common roll is 2 × 1 in (50.8 × 25.4 mm), one label per page, for Zebra, Rollo and similar 203 dpi printers.
A 10-character FNSKU still fits. On a 2 × 1 in label our generator narrows the bar to 0.25 mm, exactly two printer dots at 203 dpi, so the bars are 36.3 mm wide with 7.2 mm clear on each side.
| Label | Bars | Narrow bar | Clear space each side |
|---|---|---|---|
| 1 × 2⅝ in sheet label | 47.8 mm | 0.33 mm | 9.4 mm |
| 2 × 1 in thermal label | 36.3 mm | 0.25 mm (2 dots at 203 dpi) | 7.2 mm |
What has to fit on the label
Amazon names three label elements besides the barcode itself: the FNSKU, the name of the product, and its condition. Its list of common receiving errors includes a label missing the barcode, the FNSKU or the title, so do not drop one of them to save space on a small label.
Where the label goes on the product
Amazon's placement rule is about the old barcode, not about a position on the box: when affixing a label, cover the entire original manufacturer's barcode (UPC, EAN or ISBN) with it. A barcode left partly showing can cause receiving errors.
- Each unit needs its own label, matched to that unit.
- If the product is bagged or wrapped for prep, the barcode must be scannable without opening it, or the label goes on the outside of the prep.
- Use white label stock with removable adhesive, so the customer can peel it off.
Printer settings that keep the size true
Amazon's printer recommendations are short:
- Use a direct thermal or laser printer. Amazon advises against inkjets because the ink smears and fades.
- Print at 300 DPI or greater on a laser printer.
- Print without scaling: choose Actual size or 100%, never Fit to page.
- Scan a printed label now and then with a tethered scanner.
